Biochemical sedimentary rocks are formed primarily by which process?

Explanation:
Biochemical sedimentary rocks form when living organisms drive minerals to precipitate from water. In the oceans, organisms such as plankton, corals, and shellfish build shells and skeletons from minerals like calcite or silica. When these biological materials accumulate and lithify, they create rocks such as limestone or chert. This biological mediation of mineral precipitation is what distinguishes biochemical rocks from those formed by wind deposition, heating and melting, or erosion of preexisting rocks.
